AoU’s sample/measures uniquely allow for modeling high-burden disease pathways specified by the biopsychosocial ecological model

Biological, psychological & social domains interact at multiple levels (genes, human & environment microbiomes, stress, behavior, broad SES & environment) outlined by the biopsychosocial ecological model (BPSEM). The BPSEM specifies pathways aligned with the AoU pillars of biology, lifestyle, & environment. Simultaneous examination of the interacting domains and levels of the BPSEM is now computationally possible and... more »

Is the seminal fluid microbiome associated with incident prostate cancer risk?

Prostate cancer has long been suspected to include an infectious etiology, although no agent has been identified. It is possible that one specific virus or bacterium is not significant, but rather the characteristics of the entire microbiota to which the prostate is exposed (e.g., the abundance and diversity of all microorganisms). This may be capturable by examining the seminal fluid microbiome.

To what extent does gut permeability and dysbiosis affect systemic health?

There is a plethora of preliminary data connecting intestinal permeability to chronic inflammatory diseases. More work is needed in this area to determine causal mechanisms. Doing so could help in developing interventions and other targets in reducing chronic illnesses and improve quality of life.

Dietary and microbial-derived metabolites may modulate body weight and contribute to overweight and obesity.

Integrate multi-omic approaches (metabolomic, proteomic, inflammasome, microbiome analyses) with dietary assessment and clinical data in a nested cohort study. Dietary and/or microbial metabolites may modulate body weight and may influence other comorbidities. A comprehensive analysis of inflammatory and metabolic biomarkers of oxidative stress, nutritional assessment, short chain fatty acids and other microbial metabolites... more »

Evaluate Age-related Microbiota Changes and their impact in Health, and in Chronic Disease Prevention, Treatment and Progression

The microbiome variations have been associated with health and disease status in cross-sectional studies. There is a need to examine these associations in a longitudinal fashion and to establish baseline changes in health and disease over a lifespan. All of Us Together provides a game-changing amount of longitudinal data on enough individuals to begin to map the complex relationship between exposures (diet, antibiotics,... more »

Genetic, epigenetic, and microbiome contributions to hypertension

The goal would be to enhance our understanding of how social and environmental exposures, genomic factors, and gut microbiota interact to influence hypertension susceptibility and phenotype. This would require integrated analyses of genomic and other -omics data, exposures, and phenotype data, and could lead to insights that enable more targeted prevention and treatment. Inherent in this would be discovery of pathways... more »

Could adding fecal sampling to the "All of Us" campaign help resolve role of gut microbiome in complex disease risk?

The simple addition of fecal sample for the use of gut microbiome taxonomical assessment could prove a valuable resource for testing hypotheses about the gut flora as a target of, and contributor to myriad human health and disease states. Fecal sample collection is non-invasive and gut bacterial lab methods are becoming increasingly refined and high-throughput.

Why do some previosuly healthy infants and toddlers develop severe lower respiratory tract infections with common viruses?

This would be designed as a prospective observational cohort study of children (infants to 2 year olds) with common seasonal respiratory viral illnesses (RSV, enterovirus/rhinovirus, human metapneumovirus, parainfluenza, influenza). Those with severe bronchiolitis/pneumonia requiring hospitalizations would then be compared to those who receive care as outpatients. The analysis would include clustering based on genetic... more »

Using human microbiome data to improve pathogenesis and treatment of infectious diseases

Precision microbiome engineering could be applied to vaccine delivery, immunology, drug-resistant infections, and post-surgical infections. Specific research questions re pathogenesis and treatment: - What aspects of the indigenous microbiota mediate colonization resistance against C. difficile, as well as other multi-drug resistant organisms such as carbapenamase-producing gram negative bacteria and vancomycin resistant... more »

How can AoU data be harnessed to improve infectious diseases patient care, diagnostics, vaccinolology, and drug development?

How is precision medicine as it applies to infectious diseases different than how it is considered for Oncology or other fields?

• Time-pressured setting (e.g., initiating therapy for a hospital acquired or ventilator-associated bacterial pneumonia patient)

• Microbiome vs. human genome

• Intersections with other cognitive and procedural specialties across the board

Changes involved in the progression of T2D and development of complications is apparent at the pre-DM state or during the transition to T2D or with complications. Conducting ‘Omics’ including DNA methylation, metabolomics and microbiome studies in blood, saliva and Fecal samples allows to validate interactions of metabolites to microbiota to epigenetic regulations.

Are microbial tumor characteristics predictive of cancer treatment effects and survival?

Microbiota has been found in tumor tissues and these communities are often found to differ from the neighboring healthy tissue. Current studies tend to be small and from single cancer centers. We propose collecting tumor samples for microbial analysis in conjunction with cancer treatment data to evaluate microbial characteristics which predict successful treatment. Comparisons can be made to evaluate microbial compositions... more »

Is the human oral and fecal microbiota associated with chronic disease risk factors, such as obesity and metabolic syndrome?

The human microbiota has been found to be associated with a number of health conditions, such as obesity. However, these studies have been relatively small and from convenience samples. It is important to understand how the human microbiota impacts these chronic disease risk factors in order to prevent future disease development. We propose collecting oral and fecal samples to determine associations with many chronic... more »

Investigate whether ethanol consumption facilitates absorption of carcinogenic products from oral microbiome constituents.

Oral bacteria are known to have both beneficial and detrimental effects on oral health including carcinogenesis in the oral cavity. Since ethanol is a good organic solvent, oral bacterial enzymes and toxins may achieve greater exposure to the oral mucosa as a result of ethanol consumption, facilitating toxin access to intracellular processes. Subjects with different microbiome profiles and bacterial metabolites can be... more »
